20. Show that an acceleration of 0.67 m/s/s is the result if a force of 1000N is exerted on a 1500 kg car.

Explanation:

Given parameters:

Mass of the car = 1500kg

Force applied  = 1000N

Acceleration  = 0.67m/s²

Unknown:

Proof that the acceleration will result from the applied force on the car

Solution:

According to newton's second law of motion,

       Force  = mass x acceleration

 So;

 Acceleration  =

Now insert the parameters and solve;

 Acceleration =   = 0.67m/s²

We have shown that the acceleration is 0.67m/s²

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
